SPRING-VEHICLE.

SPECIFICATION' forming part-oi' Letters Patent No. 360,787, dated April5, 185.7.

Application filed January 24,1887. Serial No. 225,250. (No model.)

To aZZ 4whom it may concern:

Be it known that I, BRYANT A. TREAT, of Wallingford, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inSpring-Vehicles; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure I, a side view of one end portion of an -axle with theimprovement applied; Fig. 2, a top view of the same; Fig. 3, aperspective view of one of the spring-plates detached. This inventionrelates to an improvement in that class of spring-vehicles in whichdownward bends are made on the axles between the wheels, and so that thespring may hang within the bends, and thereby permit the body Y of thecarriage to hang lower than it can do on straight axles. In a commonconstruction of this class of vehicles a plate is arranged at each endof the axle, extending inward over the bend, and to the end of thisplate the corresponding end of the spring is hung. The plates aresecured to the axles by `clips. The transverse strain upon these platesis so great that they are frequently thrown out of place or line of theaxle, the platedepending upon the clips to hold them in properalignment.

The object of my invention is to more firmly hold the plate than can bedone by the clips alone.

To this end my invention consists in arranging the plate beneath theaxle, and between the collar and bend, with a pair of arms extendingfrom the inner end, one each side the axle, and to a point beyond thebend, the spring being hung to the said arms. The arms taking a bearingagainst the respective sides of the axle, take all the transverse strainfor the support of the springs, and entirely relieve the clips from suchtransverse support..

In illustrating the invention I show only one bend of the axle, bothends being alike.

A represents the axle, constructed at its outer ends with the usualarms, B, and collars C. The downward bend vD in the axle is made in theusual manner, and is a short distance from the collar. Thespring-support consists of a plate, E, (see Fig. 3,-) corresponding inwidth to the width of the axle, and in length should correspondsubstantially to the distance between the collar C and the bend beneaththe axle. At its inner end the plate is constructed with two arms, F F,formed as a part of the plate, corresponding in thickness to the widthof the axle, and of. a length so that when applied to the under side ofthe axle they'will extend inward beyond the bend, or to the point whereit is desirable to attach the spring.

' The springplate is set beneath the axle, the

two arms passing inward and upward, one

It is secured in place by the usual clips, G G. The spring H is hung tothe arms' F in the usual manner for hanging springs of this character.

The clips sustain the spring-plate against the weight suspended thereon;but the arms F F bear against the axle and resist any transverse strainwhich maybe brought upon the spring. Because the arms hold the plateagainst transverse movement, it is impossible for the plate to be thrownout of its proper position.

The arrangement of the spring-plate below the axle permits theapplication of a wood top, I, directly to the axle, and gives it theappearance of the usual wood-capped axle.

I claim- The combination of the bent axle and spring of a carriage, witha plate, E, hung beneath the axle outside thebend, the said plateconstructed with arms F F, extending inward, one each side the axle, thespring hung between said arms, substantially as described.
